A comparative study of clinical outcome in ALT free flap reconstruction using superficial or deep and single or dual recipient vein anastomosis in different sites.

Background: During the free flap surgery obtaining a suitable recipient vein is an important factor for successful outcome. As in all other flaps even in ALT flap, single or double venous anastomosis, superficial or deep venous anastomosis is still a matter of debate among the micro vascular surgeons. Though dual vein anastomosis is a time-tested method, single vein anastomosis has the advantage of reducing the operative time and hospitalization cost.
